' GEORGES PERRIER, OF STE. OROIX, SWVITZERLAND, ASSIGNOR TO G. MERMOD 81 BORNAUD, OF SAME PLACE.

MUSIC-BOX.

SPECIFICATION forming part of Letters Patent No. 368,304, dated August 16, 1887.

(No model.)

To all whom it may concern:

Be it known that I, GEORGES PERRIER, mechanician, of Ste. Oroix, Switzerland, have invented a new and useful Improvement in Musical Boxes, of which the following is a specification.

The purpose of my invention is to have the pin-cylinder of musical boxes affixed in such a way to its axis as to be easily withdrawn in view of placing another pin-cylinder upon the same axis for playing other airs.

In other words, my invention consists of a new axis for interchangeable pin-cylinders in musical boxes.

In the accompanying drawings, Figure 1 is a plan view with partial horizontal section ofthe left end of a musical box of my system. Fig. 2 is a plan view with partial horizontal section of the right end of the same. (These figures show the pin-cylinder affixed to its axis and ready to play.) Fig. 3 shows the left end, and Fig. 4 the right end, of the axis of the pincylinder, with the pin-cylinder ready to be withdrawn. Fig. 5 is an elevation of the righthand bearing of the axis of the pin-cylinder in the position it takes when the work is playing or ready to play, and Fig. 6 shows the same piece in the position it takes when the pin-cylinder is ready to be withdrawn.

In all the figures the same letters refer to the same pieces.

A is the mainspring-barrel, the tooth-range A of which engages with a pinion, B, affixed to an axis, 0, which is intended to bear the one end of the pin-cylinder, and which is supported by two bearings, D and D. Upon 0 there is affixed a wheel, E, the tooth-range of which drives the usual regulating mechanism with flywheel F.

A driving-disk, G, has its hollow axis G adjusted on one part upon the pivot C of O and on the other part upon the nave E of E. A screw, 6, is affixed to the latter and has its head sliding in a slot of the hollow axis G. A spiral spring, H, causes the disk G to take the position shown in Fig. 3, in which the pivot C does not extend beyond the disk G, and the spring H must be compressed if the disk G is to be placed into the position shown in Fig. 1, in which the pivot 0 extends enough beyond the plate G to bear the pin-cylinder I, provided with a corresponding hole. The cylinder I is further provided with a pin, J affixed to its bottom plate, T, and which engages into a slot of the disk G. The other end of the pincylinder I is supported by the pivot K of an axis, K, which is aiiixed to the bearings L L.

Said pivot K engages with a corresponding hole of the pin-cylinder I, and the latter bears at that end a second driving-pin, J, which engages itself into a corresponding hole of the disk M, which is aflixed to K by means of a screw, m.

The bearings L L are affixed to a sliding plate, N, which slides between two sliders, O O, afiixed to the plate of the work. Upon 0 there is affixed a bearing, P, with a lever, Q, oscillating on its pivot q. The lever Q, is hinged to the bearing L by means of a piece, B, so as to have the sliding plate N drawn from the position shown by Fig. 5 into the position. shown by Fig. 6, and vice versa.

When the sliding plate N that is to say, the axis K Kis placed in the position shown in Figs. 4. and 6, corresponding to the position of the disk G shown in Fig. 3, the pin-cy1- inder falls down, having its borders *5 i lying upon the bevels S S of the plate of the work until it is withdrawn and replaced by another one. Then the lever Q is thrown from the position shown in Figs. 4 and 6 into the position shown in Figs. 2 and 5, and the pincylinder is pressed against the disk G, compressing the spring H and causing thereby the pivot C to enter the corresponding hole of the pin-cylinder, while the pin J enters the corresponding hole of plate M. In this position the pin-cylinder is ready to play.

Having thus fully described my invention, what I claim is 1. In musical boxes, the combination, with the pin-cylinder I, having a hole in the center of its bot-tom plate, T, which bears beyond a pin, J, of an axis, 0 G, with pinion B, wheel E, disk G, with hollow axis G, spring H, and screw 6, substantially as shown and described, and for the purpose specified.

2. The combination, with the pin-cylinder 5 I, having a hole in the center of its bottom plate, T, which bears beyond a pin, J, of an axis, K K, with disk M, supported by the bearings L L, affixed to a sliding plate, N, sliding between the sliders O O, the bearing P, and lever Q, with pivot q and hinge R, snbstzul- :0 tially as shown and described, and for the purpose specified.
